To all whom it may concern.'

Be it lrnown that I, KURT O. WETZEL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Anchoring Device, of which the following is a specification.

This invention relates to devices embodied in concrete and similarly built-up walls and surfaces by which other articles can be secured or applied to such walls and surfaces without having to cut or work into such walls and surfaces after such walls and surfaces 'have been finished.

n `One ofthe objects ofthis invention is tosave laborin case it becomes necessary to secure or apply other articles to finished concrete walls and surfaces.

Another object is to assure a correct location of means for securing or applying `other articles to walls and surfaces.

Another object is to facilitate a securing and applying of other articles to finished walls and surfaces.

Another object is to provide a device which can be secured inside of a mold to be covered by the material when such is filled into the mold.

Another object is to provide a device which can be securedinside of a mold to `be covered by the material when such` is filled into the mold so as to leave certain parts orportions of` the device in such a condition as to allow a securingV or applying of other articles to the finished product in the mold without requiring a cutting or Otherobjects will appear from the followingdescription and appended claims as well asfrom y,the accompanying drawing,

- slightly ymodified material.

Figure l is afront view ofthe device 5 embodied in other material.y

Fig. 2 is-a side view ofFig. l seenyin the direction of the arrows 2 2. s Fig y3 is .a front,- view ofthe device and` .with surrounding buildings, for instance, it occurs very often that fixtures have to be secured to walls or ceilings at some future time at points where they are not at all desired when the building is erected or finished, ,or where such means may even be in the way or very much inconvenient. With heavy concrete blocks itis very often onlyv a matter of having some means for lifting such blocks into place when erecting, and, later on, such means should not at all showyor obstruct. At the same time such means always must be strong enough for the intended purposes.

Furthermore, it must be possible and easy to cover up such pointsv wherewsuch means are located as long as not used. VIt is also important that such. means should not shift orV get out of shape or form when concrete or similar material is being filled in or built up so as to some exten surround ,the device. l f

Withl this main point in view,-and considering other points which naturally follow from the argument occurring in the following description of the device, it becomes necessary to have-firstz acap mem- Yber,.which can easilybeplaced into a mold v so .that concrete or other similar material can befdisposed around and over it, and,

second: some anchoring means for rigidly maintaining a secure `engagement with such material/.after such material becomes a finished product. The cap member then Y naturally must be of 'such'. a` form as VKLnot -to fill 'or be` filled up byy such material. when ysuch material is poured over fit, and there. must be and. remain some means. toqwhich other articles lcanfbe securedv` or applied without obstructing ork projecting. from finished walls or-out of .finished surfaces.

f The cap '6,-A illustrated 1, is therefore made of, a form.retaining a hollow ,spaccia the ksurface of the finished product.I

if concrete or other similar material is filled in over it from the rear. The cap in the modified form 7, illustrated in Figs. 8 and 4; and the cap in the still more modified form 8, illustrated in Fig. 5, are designed with the same idea in view, and many other still more slightly modified forms can easily be provided without departing from the spirit of this invention.

For building up concrete and other similar material, it is normally necessary to provide some forms or molds into which such materials can be poured. Such molds are usually of wood for the sake of cheap ness and convenience.

The devices are therefore provided with cut-outs 9 and holes or perforations 10. Such means, however, are at such points as to prevent material from getting into the hollow of the device. A fiange 11 is therefore preferably providechhaving such cut-outs and perforations. 4Nails 12 of suitable length and strength can then naturally be used to secure the devices to the inside of such molds so as to firmly hold the'devires in place while such material is being poured into the mold.

Other cut-outs 13 are preferably provided in the device so as to allow a passing of a `bar or member 14 through and over the front of the space in the device.

The hollow of the cap member is in Fig. 1 in the drawing illustrated as of elongated form, but naturally can be of any other form as longas it allows a handling ofthe device in the manner described hereafter. The elongated form is, however, preferred for the Jfollowing reasons: After the device has been embodied into the material asset forth above, it becomes naturally necessary that fastening means must be inserted into the device, that is into the hollow behind the member 14 so as to bring such fastening means around the member 14. If then a wire or any other similar means is pushed into the hollow from eventually the point 15, it follows normally in the path along the deepest portion of the hollow to eventually the point 16 where it comes in contact with the inclined surface so as to be directed upwardly or outwardy of the hollow, then naturally being in a position thatit can be pulled around the member v14.. The" member 14 is not across the hollow at exactly right angles to the longer line through the center of the hollow, since this appears to `give the best results. The fastening meanscan be pushed through in `whatever direction it may be tried;v it is bound to come out of the hollow behind themember 14, while in the slightly modified forms in Figs. 3, 4 and 5 it eventually may come out of the hollow on the same side of the member 14 at which it has been pushed in if pushed in eventually from a point near the `a cap member o member 14, which cannot always be controlled, especially when such devices are located at inconvenient points in walls, ceilings and other places, as will easily be understood. rihe form of the hollow is however not limited as stated before.

The'member 14 is preferably made in form of an independent anchor member only passing in front of and through the hollow in the cap member, for the reasons stated above.

The preferred form ofthe anchor member is as illustrated in Figs. 1, 2 and 3. From the member 14 two members 17 eX- tend into the material in which the device vis being'used to a point to warrant a secure holding of the device within the finished product of such material. The ends of the member 14 are bent as indicated at 18 turn ing back toward the front as indicated at 19 to terminate flush with the front of the cap member 6 as indicated at 20. Bending the ends in the opposite directions tends to serve for bracing the anchor member in itself, as will'easily be understood. If such is fastened temporarily to the' side within a mold, one end 19 naturally bracingv upwardly while the other end 19 braces downwardly, it naturally follows that, if material falls upon the ends,

the lower end 19 will brace against such "falling material so as to prevent the anchor understood, without further illustration orA explanation, that, having the cap member nailed within the mold, the nails will easily pull out of such of the boards of the mold when the boards are removed from the material after the material has set, Such nails can. then beused for securing small ornamentsV or other similar things if such are to be used at such points, otherwise it is naturally desirable to Aremove such nails. In cases where the nails are not wanted, they are from the beginning placed in the cutouts 9V instead of the perforations l0, so that the nails may easily be broken out from `under the edge of the cap member, as will easily be understood. Y

. The device in the slightly modified form illustrated in Figs. 3 and 4`is of a. practiotherwise of a similar construction as the device in Figs. 1 and 2. The flange 21 is for the same Vpurpose as the flange 11 in Figs. l and 2. The anchor member` 22 -is provided with similar ends 23 projecting in opposite directions terminating flush with the front of the cap member 7 The slightly modified form illustrated in Fig. 5 is only to illustrate that it is not necessary that the cap member has to be of round form but may just as Well be of any other form as long as the sides of the cap member are so shaped that they Will deflect and direct any fastening means so as to bring it back out of the cap member When pushed into it from @ne side in the manner described above. This taper form may be cheaper than the round form in making dies for the manufacture of the cap members; it all depends on what kinds of tools are on hand, and such miner changes are naturally vimmaterial as far as the principle of the device is concerned.`

Having thus described my invention, I claim:

l. In a device of the class described, a

body member having an elongated recess in its face, the edges of the body having cutouts provided in the front face at points diagonally to the elongated recess, the body member being curved away from the edges around the entire periphery of the recess, and an anchor member disposed through such cut-outs in front of the body-recess so as to bring the anchor member flush with the front face of the body and diagonally over the recess in the body.

2. In a deviceof the class described, a body member having a recess in its face, and an anchor member disposed through and in front of the hollow'portion of the body having means projecting rearwardly from the front face of the body adapted to rigidly engage the body and anchor members Within the surface and flush with the surface of concrete and similar material When so disposed, the anchor member having extension ends curving back from Within the surrounding material toward the front to terminate flush With the front face lat opposite sides of the centerline passing through the anchor-member in the recessed face of the body-member for bracing the device when material is being poured over and around it.

3. In a device of the class described, a body member having a recess in its face and having means for securing the body to the inside of concrete molds and the like so as surface of such material when finished in the mold, the anchor member having eXtension ends curving back from Within the surrounding material toward the front to terminate fiush with the front face at opposite sides of the centerline passing through the anchor-member in the recessed face of thev body-member for bracing the device when material is being poured and disposed to engage around the device.

In testimony that I claim theforegoing as my invention I have signed my name in the presence of tvvo subscribing Witnesses.
